Mobile communication system, radio base station, mobile station, channel transmission control method, and channel transmission control program

A radio base station forming a mobile communication system comprising a plurality of radio base stations, and a plurality of mobile stations configured to communicate with each of the radio base stations and segmented into a plurality of mobile station groups, the radio base station comprising:

• means for providing a broadcast channel with first instruction information for notifying each mobile station of whether or not to receive the broadcast channel including a change announce of a paging period;
• means for providing a paging channel with second instruction information for notifying each mobile station of the presence/absence of paging information;
• and
• intermittent transmission control means for performing such a control as to intermittently transmit the broadcast channel provided with the first instruction information and the paging channel provided with the second instruction information on a control channel.

A mobile station forming a mobile communication system comprising a plurality of radio base stations, and a plurality of mobile stations configured to communicate with each of the radio base stations and segmented into a plurality of mobile station groups, the mobile station comprising:

• instruction information detecting means for detecting first instruction information provided to a broadcast channel and second instruction information provided to a paging channel, the broadcast channel and the paging channel being transmitted on a control channel from a radio base station;
• broadcast channel analyzing means for analyzing the first instruction information detected by the instruction information detecting means and for determining whether or not to receive the broadcast channel;
• and
• paging channel reception control means for controlling whether or not to receive the paging channel, based on the second instruction information detected by the instruction information detecting means.

A channel transmission control method from a radio base station to a mobile station at a plurality of radio base stations, and at a plurality of mobile stations configured to communicate with each of the radio base stations and segmented into a plurality of mobile station groups, the channel transmission control method comprising the steps of:

• the radio base station's
• providing a broadcast channel with first instruction information for notifying the mobile station of whether or not to receive the broadcast channel including a change announce of a paging period;
• providing a paging channel with second instruction information for notifying the mobile station of the presence/absence of paging information;
• and
• performing such a control as to intermittently transmit the broadcast channel provided with the first instruction information and the paging channel provided with the second instruction information on a control channel.

A channel transmission control program for implementing a channel transmission control from a radio base station to a mobile station at a plurality of radio base stations, and at a plurality of mobile stations configured to communicate with each of the radio base stations and segmented into a plurality of mobile station groups, the channel transmission control program making a computer function as:

• means for providing a broadcast channel with first instruction information for notifying the mobile station of whether or not to receive the broadcast channel including a change announce of a paging period;
• means for providing a paging channel with second instruction information for notifying the mobile station of the presence/absence of paging information;
• and
• means for performing such a control as to intermittently transmit the broadcast channel provided with the first instruction information and the paging channel provided with the second instruction information on a control channel.
